Veteran California punk rockers Social Distortion premiered their new short film for "Machine Gun Blues" at a red carpet event in Los Angeles Thursday night.  In addition to debuting the video, the band performed a one-hour set, and both were streamed live on the Internet at RollingStone.com.  "Machine Gun Blues" is the band's first single from "Hard Times and Nursery Rhymes."  No word on when the film will become available again, but check out the trailer below.
